Since many of us are doing plug change, I have a question about the resistor vs non-resistor plugs,

The OEM plug in most of our W210 is F8DPER which I believe is a non-resistor plug that's no longer available
The replacement is F8DPP322, FR8DPP333 which I believe is resistor plug

Here's the problem, several recognized member from mercedesshop.com swear by NOT using resistor plug in place of non-resistor plug - claiming problem with

Bad wires, cap, rotor and/or wrong spark plugs can wreck your ignition module
Is it going be a problem? Not wanting to cause a concern or bring up an old discussion, just want input.

Regards,

Either get

the fr8dpp33 or the best match to the oem bosch platin is the NGK 7090 great plug,performs flawlessly and is only about $2.75 at most auto stores.
You have no cap nor rotor,it is all controlled by the cam sensor and in effect a crank trigger which in the case of the m112 and m113 engines is the crank position sensor.The wires if popped off with the 17mm boot tool will last forever and coil on plug ignitions rarely see failures.
So use the ngk 7090,no anti seize,they are plated out of the box.
have the engine cooled down and have fun.:D

So I believe it sounds like it'd be a problem with old engine having rotor, cap (distributor) when using resistor plug?

I've the fr8dpp33 plugs and waiting on the tool. Long weekend to do plugs, should be a blast. :thumbsup:
